How do we make a rom with the best battery life? In this thread, we will make it.
Food for thought:
Underclocking
*#*#4636#*#* configurations (wcdma, gsm only, what is best)...}These two will help with the "mobile network" process,
lower gprsclass........................................................}that uses so much in the "battery usage" breakdown in settings
undervolting
wifi scan time
2g networks only
Battery-optimized kernel
NO Swap or Ram Hack or CompCache
ETC.
Anyone have ideas.
I will now list the rom with the best battery life (that i've ever tried)
Htcclay's Superfast 1.3.3
Please post the roms you think have best battery life.
I'm going on a vacation and will not have a charger handy at all times. What is best for me??? contributions are welcome (until we make the ultimate rom discussed in this thread.)
gee the forums are slow today... reserved
enomthers official AOSP 1.6..
i am running superbad cm51.2.3gj4 and i get around 24-30 hours on a single charge
I'm running SuperD 1.11 with SetCPU @ 384/128 and get about 4 days on a single charge. 3 days with heavy usage and 6 days without any data transfer (only sms and sometimes phone calls).
This is by far the best ROM for battery life I've used. Haven't tried Superfast 1.3.3.
Is it possible to undervolt G1s or MT3Gs?
jumped to almost every 2.1 rom out, Chromatics 3.5 being the last 1 and all of them are battery hogs. I was tired of it so decided to revert back to 1.6 roms (htc clays super csdi) and must say that Im staying here..Its much faster and the battery life nearly doubles. and also with ADW launcher, it gives you everything you need besides MT. Again battery is amazing on csdi roms. just make sure you turn off modder cpu and turbo mode in supsetup and use setcpu clocked at 128min 528max..

I agree. Battery life with 2.1 roms is terrible compared to 1.6 roms (which last up to 50% longer).
Something doesn't seem right with 2.1 roms. I hope Froyo will be better.
i really like the idea of a battery-optimized rom for g1/32b.
i also made the experience that 1.6 roms are better in terms of battery life than 2.1 based roms. they also are much faster
btw: the best 2.1 based rom for battery is speedtest 1.2
I agree that the 2.1 roms are all terrble, and that something uniform must be wrong with all of them in order to have ALL of them have such bad battery
wow that was horrible... im tired
I'm glad that many of you are interested in a battery-optimized rom. I'll be trying out SuperD today, but its use of swap is detrimental to battery life... I'll have to see.
Any other suggestions?

that's attractive... are you using ram hack or not? swap/compcache settings?
I remember some of the older 2.1 (Not CM 5 based) roms being not nearly as bad on battery life, like KingKlick's. It wasn't as fast and stable as Cyanogen's, but I remember being able to easily go through a full day and half without needing to charge (with moderate use, and an 8 hour gap of nothing for sleep). Maybe digging some of them up and doing some tests?

i remember gamercore tweeted about openeclair 1.1 being really good, and i tried it, and it was quite good, but the rom sucked and it was hardly comparable to donut.

Hmmm, well didn't OpenEclair go up to 2.2.1, before Wes joined CyanogenMod? Do we know what the big difference is between those older roms and Cyanogen's implementation and why there's such a drastic battery (and performance) difference? I always thought it was just lack of drivers and Cyanogen did extensive work to various driver projects to get workable drivers. Would his drivers be the cause of poor battery life? I'm grasping at straws here, but that seems like one of the only things it could be to me.

No compcache/swap but with ram hack.
2.1 roms are using a lot more ram then 1.6 roms.
With 1.6 I have about 40 to 50 MB of free ram after using taskiller.
With 2.1 only 20 MB. This is just a guess but whatever is using these 20-30 MB of ram might be partially responsible for the battery drain.
If additional battery drain is the nature of Eclair (which clearly wasn't built with our "old" phones in mind) then Froyo might bring some improvement.

I've noticed the same thing. 2.2 seems to be better... but jubeh's rom quit apps in the background much quicker than the other guy who compiled from source and posted in this forum (his had no wifi tho, but i liked it better because of memory management)... i don't know what the difference was, but i liked the other guy's froyo rom better.
Back on topic, I still think that 1.6 remains the best rom for battery life.

and I heard that 1.10.2 was even better than 1.11 for battery life... (dusty donut as ben called it), is this true? and i can't assess how much changed between 1.10.2 and 1.11 because ben buchacher's changelog is down... somebody help me out here?

v 1.11 release date : 2010 04 29
Change Log:
-Updated Frameworks and Settings from latest Cyanogenmod Donut tree
-Proxy Settings in Wireless Settings
-WIFI in Airplane mode
-USB Debugging notification option
-5 minute screen timeout option added
-Updated Working Renice script -thanks to merlos
-Media to SD -thanks to merlos
-Exchange Work Email app fixed
-Battery percentage option in SpareParts
-Live Folder FC fixed
-Portrait / Columns bug fixed
-Remove Launcher script – This fixes the battery life.-thanks to merlos
– from terminal type remove_launcher then the one you want to remove nexus or stock
—-EXAMPLE: remove_launcher stock
-Other Crap
Maybe the claim that 1.10.02 has better battery life is because of the "Battery percentage option in SpareParts" Some people think it drains the battery. For users of 1.11 I recommend to disable it (Settings -> Spare Parts -> Battery Status Display)
I would like to add something about RAM hack... Some games don't appear as "3d" but still need that RAM. As I remember running a 3d game on a ROM with the RAM hack would drain your battery horribly fast and make the game horribly laggy. Well some games can handle the lag, but still destroy battery life.

I think the main idea about this thread/rom is to make a rom for the g1 that makes for great battery regardless, so ram hack could be an option that will be disabled for this rom.

I know what the thread's about, silly. But RAM hack has a great chance of just destroying the whole "better battery life" aspect and I don't think there's really a way around that, that's all I was trying to say.
If you do end up making a ROM with crazy good battery life, I'll definitely keep it around for vacations. I made the mistake of going on vacation with a 2.1 ROM - my phone lived for two days out of a week (and that's with charging every chance I got) so I'm all for you. =]

I know there has been a great deal of mix up on SBC (or trickle full charging) but i will say I have used it for a while, on my EVO, with terrific results with absolutely no problems. It adds almost 2-3 hours worth of battery life to my EVO. I was wondering if any of the DEV's would be willing to tackle this and make and undervolted (HAVS), SBC stock kernel for the Inspire 4G that would run with sense. My gf's battery life is just atrocious as was mine when I first got my EVO4g. The evo does have one plus and that is it has a 1500 vs a 1230 mah battery. I would be very happy to donate. The Kernel above is the one I use and it is great and stable. I know they are different frameworks and operating systems but I figure it is a start. Thanks in advance to anyone that wants to attempt this.
Hey everyone, i just upgraded to a Nexus S 4G this morning from the ol samsung transform, and i was planning on applying cyanogen but then i messed with the phone a bit, did root and restored a couple of my game apps...it seems to work with very nice speed, only serious issues ive noticed are just with the signal, sensitivity of keyboard, and i havnt had time to see battery life yet..
But i was wondering, since the stock rom is so clean and fast, why are we putting on different roms like cyanogen?
More importantly, as far as kernel, whats the best kernel right now for nexus 4g? im running stock kernel, but naturally and ideally id like even more speed(not sure what id use it for, but always nice), better battery life, and better data signals..
ive been reading about overclocked kernels a little bit and such, so basically im wondering about what you guys would say to all this? should i change rom &/Or kernel? to what? why? does overclocking at 1.4ghz like these kernels say have any negative side effects? things like that.
Thanks for your response!

There are quite a lot of things that can be changed by flashing a custom ROM. Cyanogen is reported to be more responsive than stock android, and a slight improvement on battery life and performance. Also, with other ROMs like MIUI you can completely change the entire GUI basically. The lockscreen becomes changeable by one click in the themes app. I've also noticed a slight improvement in battery life/performance and responsiveness.
Also, with regards to kernels, they add extra features (like voodoo sound, BLN notifications, UV'ing, OC'ing, etc). Now if you're looking to overclock your CPU AND save on battery life then that is probably not going to happen. If you OC the CPU you'll as a result draw more battery power when it reaches it's peak. Hence why I went with the TEUV88 kernel. This kernel undervolts the CPU yet manages to give me the same performance as the stock kernel. It runs extremely nicely and the battery lasts me about 24-30 hours on moderate usage where as before I was getting around 16.
Hope this helps.
Edit:: note that both undervolting and overclocking can be dangerous for any phone. The kernel developers put their kernels through testing though to ensure they are stable enough for most people (I hope anyways). But be aware that it is possible to damage the hardware be either of these methods.
yeah im looking at more undervolting for battery life cause current performance seems great for me as of this point. but i mean cyanogenmod doesnt change much since its built on gingerbread, its just slightly more customized, but on the actual performance side, it is a slight increase? so whats the best kernel for undervolting and still getting stock performance or more? im guessing its the one u just mentioned? cause i saw a voodoo kernel or something on main dev page and itwas undervolted and OCed to 1.4 i think...idk.
Yeah you might be talking about the matr1x kernel. It ocs to 1.44 and is uved also. Plus has voodoo sound, bln and bld. Some people have issues with cm7 and some don't. I really don't like the look of miui so I can't say for it. But I use decks 1.3d with zero issues and matr1x kernel with zero issues along with heavy use 4+ hrs screen time in over 12hrs. Personally running 1.44 your phone will prolly lock up but I run 1.2 non stop no freezes or lockups or reboots. Try them and see qhich ones fit you and what you like.

I'm still on stock with mine and honestly, I don't need anything else... i get 12-15 hours of moderate use and i don't really know what lag is because i never experience it with my phone.
The above posters are correct in everyway. I mean it definitely comes down to preference. I was averaging about 13-15h on my stock kernel/rom but my phone would be basically completely dead.
I switched to TEUV88-rammstein2 (Trinity Undervolted rom). It has Voodoo sound, BLN (backlight notification), and with todays update it has touchwake mod. So as you can see my phone lasted 15h (still with 35% battery left) with 3h of screen on, and 45m of audio streaming, and lots of texting.

Hello I am wondering whats the best kernel for battery life on CM7 would it be faux or stock? And plus can I just install the faux Cm version start at 1.0 ghz to 1.4ghz, so by overclocking it means it will have less battery life? Could I just install that kernel and leave it at 1.0 ghz? And is the faux kernel better than the CM7 stock in terms of battery and what about performance?
New to this stuff!
Thanks people!
What CM7 are you running? It makes a big difference. Also, battery life is different for every person. So to say one kernel is better than another is based on your use. Now I did notice a difference in battery life and performance when I flashed Faux's kernel. But best advice? Wait a couple days on stock, see how it is. Then flash Faux's or the any other kernel(as long as it CM7 based of course), to compare the results. Of course when your comparing make sure your phone usage is the same, or as close as you can get it

Ya. I flashed the DS OC/UV v.0.4.8 first but like faux says the battery readings were crazy, going up and down all time, I didnt know how much battery I had left. And this was after I calibrated my battery of course. Im using the CM OC/UV v.0.4.8 kernel and its great! Great performance and awesome battery life! Right now I got 38% left with moderate to heavy use on 10 1/2hrs. I posted a few screenshots of my battery use using Battery Monitor Widget Pro. I couldnt post the battery use one cause I rebooted my phone a couple times changing my theme. It reads like 2hrs on battery instead of almost 11. Also I posted a Antutu benchmark score as well. Try one see if it works, no two chips are the same, if it doesnt, he's got 4 different kernels. Plus there's the other kernels that I havent tried yet. Hope this helps!
Overclocking will reduce your battery life but increase your phone's performance. Use an app like SetCPU to choose your clockspeeds and voltages. I don't recommend messing around with voltages until you're much more familiar with over/underclocking.
I've used faux's kernels off and on and never been able to get my G2x to be rock solid stable versus the cyanogenmod kernel but it certainly did increase my battery life by a noticeable amount. Right now I'm running the Trinity ELP kernel and undervolted it even further and I've had absolutely zero issues. If you try faux and don't like it, give Trinity a try.
I prefer Trinity ELP or Faux DS versions if I am in battery savings mode depending on the ROM I am using.
Hi!
Ok, i'm not good in writing especially in english so here we go
From all kernel that has been released lately, which one do you recommend for having the best battery life in term of standby??
My opinion is Sebastian's kernel in ARHD 6.5.1
it gave me mostly 2 hours for 1%
but i have new problem now cause i flash ARHD 6.5.3 and then restore boot from 6.5.1 NAND back up and now my wifi gave me error
(but this is my problem, not yours )
Come on guys, give me your opinion
I'm currently running Hyper NonSense with the default kernel - I think it's Faux that's cooked into the ROM but unsure of this. Between the ROM and the kernel, I'm getting the best battery life I've seen with this phone. Easily have 30-50% left at the end of the day with moderate use; haven't actually benchmarked it more carefully than that.
Any update on this? My sensation doesn't even last a day...
Best kernels right now are Faux kernel
Sebastian FM
Bricked kernel
I myself have found that bricked uses the less battery, but try them yourself and decide which suits your needs.
I'm using Faux right now with HyperNonSense and I would say it's a good balance between battery saving and performance. One thing to keep in mind is that the higher you OC the more juice it'll drain. So far I've always capped my CPU to 1.24Mhz and I've never had an issue with performance. During light use I can get more than 30 hours in a full charge. If it's a moderate use, I'm still able to touch 24 hours. Oh yeah I'm using Anker 1900mAh.
